Introduce a temperature control system based on STM32 and ADS1248. The system consists of Pt100 thermistor acts as temperature sensing element and a thermoelectric cooler acts as temperature control element
and temperature is controlled using digital PID algorithm. The circuit of the system is easy to design and realize and the system is with great control flexibility. Experimental results show that the system can effectively achieve temperature control and the precision up to ± 0. 1 ℃.
